What represents Karel's starting position in a Karel world?

Karel's starting position in a Karel world is effectively identified by street and avenue coordinates. In the context of Karel programming, the grid is defined with streets running horizontally and avenues running vertically. Each point on the grid where Karel can occupy a space is determined by these coordinates.

When Karel starts, it does so at a specified point defined by its street and avenue coordinates. This means that the programming environment understands exactly where Karel begins its tasks. The coordinates help to precisely locate Karel within the grid for navigation and task execution.

While direction plays a significant role in determining which way Karel faces upon starting, it is the combination of these street and avenue coordinates that fundamentally establishes Karel's initial position in the Karel world. Other attributes like color, shape, and functionality pertain to Karel's characteristics or capabilities, but they do not define where Karel is placed within the grid at the start.
